Describe reproductive structures of hibiscus and pteridophytes respectively

Answer 1

Hibiscus:
- Hibiscus plants have perfect flowers, meaning that each flower contains both male and female reproductive structures.
- The male reproductive structures, called stamens, consist of anthers that produce pollen.
- The female reproductive structures, called carpels, contain the ovary where the ovules are found.
- Pollen must be transferred from the anthers to the stigma of the carpel for fertilization to occur.
- After fertilization, the ovary develops into a fruit containing seeds.

Pteridophytes:
- Pteridophytes are seedless vascular plants that reproduce through spores.
- The reproductive structures of pteridophytes are found on the underside of the leaves, in structures called sporangia.
- The sporangia produce spores through meiosis, which are released into the environment and eventually germinate into new gametophyte plants.
- The gametophytes produce gametes (eggs and sperm) that fertilize to form a zygote, which develops into a new sporophyte plant.
